IMPROVEMENT IN BUCKLES FOR HARNESSES, 81.0.

Specification forming part of Letters Patent No. 4 3,787, dated October 25, 1864.

To all whom t may concern:

Beit known that I, L. D. CoWLEs, ot' Armada, in the county of Macomb and State of Michigan, have invented a new and Improved Buckle for Harnesses and for other Purposes 5 and I do hereby decla-re that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis an outer or face view of my invention; Fig. 2, a side view ofthe same; Fig. 3, a longitudinal section of the saine, taken in the line a: Fig. 1; Fig. el, a detached view of the cani-lever frame pertaining to the saine.

Similar letters of reference indicate like parts.

This invention consists .in using, in connection with the frame or body of the buckle, a stirrup and cam-lever frame, arranged in such a manner that the strap may be very readily taken up and let out and a buckle obtained without any drilling or riveting whatever.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the frame or body of the buckle, which maybe constructed in any proper or desired forni, and provided at each side, near one end, with a lip, B, said lips projecting at right angles from the frame or body A and parallel with each other. Each lip B is provided at its outer end with a iiange or projection, a, and these flanges extend outward from the lips at right angles.

C is a stirrup, of loop form, and may be deseribed as being composed of two parallel bars, b b, connected by rounded and depressed ends c c, the latter extending down at the outer sides or edges of the frame or body A.

D is a lever-frame, the shape of which is shown clearly in Fig. 4. At each end of this frame there is a cam, E, the shape of which is shown in Fig. 2, and these cams are fitted between the ilanges a of the lips B and the depressed ends c of the stirrup C, as shown clearly in Fig. 2.

The frame or body A, with its lips B and flanges a, are all cast in one piece. The stirrup U is also cast in one piece, as well as the lever-frame D and cams E E, the latter being sprung in proper place between the flanges ct of the lips B and the ends c of the stirrup.

From the above description it will be seen that when the lever-trame D is raised, as shown in red in Fig. 2, the strap F shown may be. readily slipped between the stirrup and frame or body A of the buckle, and by pressing the lever-frame D toward A the cams E E will force the stirrup C in close cont-act with strap F, firmly clamping the same between the stirrup C and the body or frame A. The other strap, G, (shown in red,) is attached to the end ot' A, opposite to the end where the stirrnp C is placed 0r fitted.

Thus it will be seen that by this arrangement all riveting, drilling, Ste., are avoided in the construction of the buckle, and consequently a very economical and strong buckle is obtained.

l claim as new and desire to secure by Letters Patent- The. stirrup C and lever-frame D, provided with the cams E E, in combination with the fratrie or body A, provided with the lips Il, having flanges c at their outer ends, all being arranged substantially as and for the purpose set forth.
